[new-theme | OpenAIRE theme]: Small fixes & additions.

1. background.css: :not(.uk-preserve-color) removed from uk-background-primary | color is defined separately for primary backgrounds (uk-preserve-color affects only text color).
2. button.css: NEW variable --button-primary-color-hover.
3. text.css: Set --font-default-color: #4b4b4b; | Apply primary color to primary section too.
